KLX 250 carb question
 

Hi all I had a post last week about my klx running to rich at low RPM's have a slip on and everything is with in spec. After looking everything over I noticed the needle jet holder dosnt look like it is screwing all the way flush into the carb. Originally I was not the one to disassemble the carb, my cousin did. Would anyone have a pic of the needle jet holder from the side. It looks like it should screw all the way in. With out the needle jet installed in screws all the way flush. Im not sure whats going on. It looks like the needle jet only goes in one way. With the needle jet installed there are a few threads still showing. would anyone have a detailed instruction on how to install the needle jet and holder. Looks pretty straight forward. Its the only thing i can think of for this constant rich condition.

thanks
